Gas Permeable (GP) Contact Lenses

Summary Content

At Health Today, we offer Gas Permeable (GP) or Rigid Gas Permeable (RGP) contact lenses as a durable and health-conscious alternative to soft contacts. Crafted from a hard, oxygen-permeable material, GP lenses are designed to let your eyes "breathe" by allowing oxygen to pass through to the cornea, enhancing both comfort and eye health. Despite being less popular than soft lenses, the benefits of GP lenses, including their contribution to eye health, hygiene, and potentially slowing down myopia progression, make them a valuable option for many.


GP or RGP lenses offer several benefits, making them a compelling choice for those considering contact lenses:

  • Health and Hygiene: GP lenses are less prone to harbor bacteria due to their lack of water content, reducing the risk of eye infections. The material resists protein deposits, ensuring the lenses remain clean and clear.
  • Durability and Maintenance: Made from a robust material, GP lenses are less likely to tear and are straightforward to clean and disinfect. With proper care, a pair can last a year or more, offering significant cost savings over time.
  • Comfort and Custom Fit: Custom-made to fit the unique curvature and size of your eye, GP lenses provide a comfortable fit. Their oxygen transmission capabilities can reduce dry eye symptoms, enhancing overall comfort.
  • Sharp and Stable Vision: The rigid material of GP lenses maintains its shape on the eye, providing consistent, sharp vision without the dehydration issues common with soft lenses.
  • Cost-Effectiveness: The longevity of GP lenses makes them a cost-effective solution compared to frequently replaced soft or disposable lenses.
  • Astigmatism Correction: GP lenses are particularly effective for individuals with astigmatism, offering clear and stable vision where soft lenses may not.

Adapting to GP lenses can be a period of adjustment, especially for those accustomed to soft lenses. Initial lens awareness, feeling the edge of the lens with each blink, may be noticeable but typically diminishes as you adjust to the lenses. Many wearers report that after this adaptation period, GP lenses are as comfortable as, if not more so than, soft lenses.

GP Lenses for Myopia Control and Ortho-K: Emerging research suggests GP lenses may play a role in myopia control, particularly in children, by slowing the progression of nearsightedness. They are also utilized in Orthokeratology (Ortho-K) for overnight corneal reshaping, offering clear daytime vision without the need for lenses or glasses.
